Abstract

Kinetic simulations of charge transfer in the framework of the conduction band/valence band model are described which investigate the effect of 5.08 eV photon bleaching on the optical absorption spectrum of irradiated LiF:Mg,Ti (TLD-100). The decrease in intensity of the 3.8 eV and 4.3 eV bands, newly discovered sub-entities of the 4.0 eV composite band, is interpreted as arising from the participation of holes released by capture of electrons at V₃ two-hole-centers. The simulations also require highly efficient electron transfer from the excited state of the F center to the V₃ center which is necessary to guarantee an adequate supply of released holes following the V₃-V_k transformation.
